Book excerpt: Emily Berry's Dear Boy was described as a 'blazing debut', winning the Forward Prize for Best First Collection in 2013. Stranger, Baby, its follow-up, is marked by the same sense of fantasy and play, estrangement and edgy humour for which she has become known. But these poems delve deeper again, in their off-kilter and often painful encounter with childhood loss. This is a book of mourning, recrimination, exhilaration and 'oceanic feeling': 'A meditation on a want that can never be answered.'
